1)A sample of red blood cells are placed in an isotonic solution and viewed under a microscope. Then, sugar is added to the solution to create a hypertonic solution. The sample is then looked at under a microscope again. what happened to the red blood cells after the sugar was added to the solution?

A- The red blood cells released water through osmosis. The release of water helped the blood cells take in more sugar for energy.
B- The red blood cells absorbed water through osmosis. The absorption of water helped the blood cells take in more sugar for energy.
C- The red blood cells released water through osmosis. The release of water helped the blood cells keep a similar concentration of solutes as the outside solution.
D- the red blood cells absorbed water through osmosis. the absorption of water helped the blood cells keep a similar concentration of solutes as the outside solution.

2)Which of the following is an example of microevolution?

A- the formation of four new species of fish in a lake over thousands of years.
B- a mass extinction that occurs because of major environmental changes in a habitat
C- a change in the frequency of body color in a species of beetles
over time
D- the formation of two new species of rodent have been isolated by a mountain range

3) a species of dark green trees is spread over a very large terrain. over a long period of time, mountains form in this area and the trees became split by the new formation. later, the trees on the east side of the mountain are all light green.

Over time, the light green and dark green trees spread to a new field that is not separated by the mountains. both types of trees are seen in the same field. however, the trees cannot produce any fertile offspring together. which of the following provides the best explanation as to why the two populations of trees cannot produce fertile offspring?

A- the trees on the west side of the mountain retained their original phenotype that became unique to their population
B- the trees on the east side of the mountain developed a new phenotype, which made them unable to produce fertile offspring.
C- the trees on the east side of the mountain experienced many genetic mutations and recombinations unique to their population
D- the trees on the west side of the mountain could not adapt to the new barrier, which made them unable to produce fertile offspring.
